Neverwinter exploit results in emergency maintenance, no rollback

Neverwinter's emergency maintenance this afternoon fueled speculation among players that another currency exploit was to blame and a rollback was imminent, but Perfect World Community Manager Akromatik says no rollback is planned. On the official forums, he wrote,

Due to an exploit we had to bring down the servers for an emergency maintenance. The exploit was brought to our attention by our fantastic community. Your efforts, enabled us to find and implement a fix as soon as possible. Unfortunately the fix required downtime and will likely require additional maintenance following our investigation. While there is no rollback planned, we will be taking action against people who abused this exploit. Thank you for your patience, diligence and understanding. We will keep you updated as the situation develops.

A serious currency exploit in May of 2013 after the game had soft-launched into "open beta" did in fact result in a rollback.
